Medical Xpress / Early signs of Parkinson's can be identified in the blood

A team led by researchers at Chalmers University of Technology, Sweden, has succeeded in identifying biomarkers for Parkinson's disease in its earliest stages, before extensive brain damage has occurred. The biological processes ...

Phys.org / The first direct observation of a liquid charge density wave

Charge density waves (CDWs) are ordered, crystal-like patterns in the arrangement of electrons that spontaneously form inside some solid materials. These patterns can change how electricity flows through materials, in some ...

Phys.org / Cuttlefish use polarized light to create a dramatic mating display invisible to humans

Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal courting rituals. Less obvious ...

Phys.org / King's Trough: How a shifting plate boundary and hot mantle material shaped an Atlantic mega-canyon

The King's Trough Complex is a several-hundred-kilometer-long, canyon-like system of trenches on the North Atlantic seafloor. Its formation was long thought to be the result of simple stretching of the oceanic crust. An international ...
